If you get to the position of having more than a few hundred players online, you'll want to be thinking very seriously about distributed servers, most machines couldn't cope with that sort of overhead (granted, some very pumped SMP/ram-by-the-excavation-load superbeasts can), and/or setting a cap limit on the maximum your machine seems to cope with (obtained through trial and error), with some sort of login-time limit for existing players (think BBS). Even not using a thread for each player, you'll still be processing a vast amount of information, and doing vast amounts of work, which would floor you anyway. :) -- Regards, -Matt Chatterley Spod: <A HREF="http://user.super.net.uk/~neddy/spod/spod.html">http://user.super.net.uk/~neddy/spod/spod.html</A> </PRE> <!--X-Body-of-Message-End--> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <HR> <!--X-Follow-Ups-End--> <!--X-References--> <UL><LI><STRONG>References</STRONG>: <UL> <LI><STRONG><A NAME="00855" HREF="msg00855.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></STRONG> <UL><LI><EM>From:</EM> J C Lawrence <claw#under,engr.sgi.com></LI></UL></LI> </UL></LI></UL> <!--X-References-End--> <!--X-BotPNI--> <UL> <LI>Prev by Date: <STRONG><A HREF="msg00890.html">Re: [MUD-Dev] Character development [was Re: ]</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg00892.html">Re: [MUD-Dev] Parlez vous NPC?</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg00879.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg00826.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="index.html#00891"><STRONG>Date</STRONG></A></LI> <LI><A HREF="thread.html#00891"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> <ul><li>Thread context: <BLOCKQUOTE><UL> <LI><STRONG>Another recruit for the list?</STRONG>, <EM>(continued)</EM> <ul compact> <ul compact> <ul compact> <ul compact> <LI><strong><A NAME="00817" HREF="msg00817.html">Another recruit for the list?</A></strong>, Joel Dillon <a href="mailto:emily#cornholio,new.ox.ac.uk">emily#cornholio,new.ox.ac.uk</a>, Sun 22 Mar 1998, 15:29 GMT </LI> <LI><strong><A NAME="00855" HREF="msg00855.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></strong>, J C Lawrence <a href="mailto:claw#under,engr.sgi.com">claw#under,engr.sgi.com</a>, Mon 23 Mar 1998, 20:38 GMT <UL> <LI><strong><A NAME="00872" HREF="msg00872.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></strong>, Joel Dillon <a href="mailto:emily#cornholio,new.ox.ac.uk">emily#cornholio,new.ox.ac.uk</a>, Tue 24 Mar 1998, 08:16 GMT <UL> <LI><strong><A NAME="00879" HREF="msg00879.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></strong>, J C Lawrence <a href="mailto:claw#under,engr.sgi.com">claw#under,engr.sgi.com</a>, Wed 25 Mar 1998, 00:17 GMT </LI> </UL> </LI> <LI><strong><A NAME="00891" HREF="msg00891.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></strong>, Matt Chatterley <a href="mailto:matt#mpc,dyn.ml.org">matt#mpc,dyn.ml.org</a>, Wed 25 Mar 1998, 08:17 GMT </LI> </UL> </LI> </ul> </ul> <LI><strong><A NAME="00826" HREF="msg00826.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></strong>, Ben Greear <a href="mailto:greear#cyberhighway,net">greear#cyberhighway,net</a>, Sun 22 Mar 1998, 20:00 GMT <UL> <LI><strong><A NAME="00829" HREF="msg00829.html">Re: [MUD-Dev] World Persistence, flat files v/s DB v/s ??</A></strong>, Jon A.
